LEAD-WIRE TERMINAL.

Specification of Letters Patent. Patented J an. 29, 1918.

Application filed July 10, 1917. Serial No. 179,614.

. To all whom may concern:

Be it known that I, BERNARD H. Ons- TRICHEB, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Lead-Wire Terminals, ofwhich the following is a specification.

With the usual manner of connecting the ends of lead wires to various forms of-terminals to which they are attached, diflicultieshave been experienced not only in making the connection, but also in so placing;

the lead wires as to prevent short circuits and also to prevent the breaking of the wire.

I am aware that to overcome these difficuL ties various forms of lead wire terminals have been constructed in some of which the terminal has been permanently fixed to the end of the lead wire and provided with a socket or means by which the same has been connected to a terminal to which it is to be secured, and it is to this form of lead wire terminal that my present invention relates, the object of the same being to provide a simple inexpensively constructed lead wire terminal in and to which the end of the lead wire may be readily connected and one in which also the extremity of the insulation covering the lead wire may be gripped in order to protect the insulation and also to assist in securing and maintaining the bared portion of the lead wire in position in the terminal. In carrying out my invention my improved lead wire terminal preferably comprises a body member stamped up of metal of suitable electrical conductivity and provided with oppositely disposed bands'between which the bared end of the lead wire may be received and clamped by forcing the bands inwardly by means of a blow from a hammer or otherwise, the terminal being provided with a .suitable socket or similar connection at one end and at the other with a clamp for engaging. and protecting the extremity of the insulation surrounding the lead wire to which the terminal is connected as will be hereinafter more particularly described. I

In the drawing: Figure 1 is a plan of my improved lead wire terminal.

Fig. 2 is an edge View of the same.

Fig. 3 is an end view of the same.

Fig. 4 is an edge view of anothewform of the terminal Fig. 5 is an'end view of the form shown in Flg. 4;, and V Fig. 6 is a View of the form. of invention shown in Figs. 1, 2 and 3 illustrating the manner in which the same is connected to the end of the lead wire.

Referring to the drawing and particularly to Figs. 1, 2 and 3, in carrying out this invention I employ a body member 10 made of copper or any other suitable material of good electrical conductivity. This preferably constitutes two plates Hand 12 bent or folded over each other as indicated at 13 so that the plate 11 becomes an obverse plate, and the plate 12 a reverse plate. In similar positions these plates are provided with apertures 14 and 15 so that when folded over each on other these apertures register one another forming a socket adapted to receive a bolt or other part of a terminal to which the lead wire terminal is to be connected.

The reverse plate 12 is provided with a pocket 16 and asemi-circular band 17 spaced therefrom, while the obverse plate.

11 is'e rovided with semi-circular bands 18 and 19 spaced from each other and as illustrated in Fig- 2 the band 18 is intermediate of the pocket 16 and the band 17 while the band 17 is intermediate of the bands 18 and 19. The reverse plate 12 terminates in an outwardly extending member 20 having a the bands 17 and'18 so that its extremity lies in the pocket 16, the end of the insulation coming approximately to the right hand side of the band 19 as viewed in Fig. 2. The ends 21 and 22 of the U-shaped clamp are then passed over the end of the insulation and clamped thereto by a blow of a hammer or any other similar means so as to rigidly connect the parts and then by a blow of a hammer or otherwise, the bands 17, 18, and 19 as well as a portion at least of the pocket 16 arefiattened so as to secure and make a good electrical contact with the intervening bared end of the lead wire,

Nil

Referring to Figs. A and 5, instead of folding the body member on itself as indicated m Figs. 1 to 3 inclusive, the body 'member may consist of a single band of metal indicated at 24., In a suitable positionv this is provided with a pocket 25 and on the same side with a semi-circular band 26, .the end of the body member terminating in an outturned portion 27 the extremity of which is a U-shaped clamp having ends 28 and 29 in a semi-circular base 30, corresponding in radius to that of the band 26. U11 the opposite side of the terminating member 24 the same is provided with bands 31 and 32 which are staggered in their relationship to the band 26 and the pocket 25. The manner in which this form of the terminal is connected to the bared endof an insulated lead wire is precisely similar to that hereinbefore described in connection with the form of the invention shown in Figs. 1 to 3 inclusive.

ltwill be understood that other similar forms of lead wire terminals may be stamped up by dies in shapes generally corresponding to those hereinbefore described without departing from the nature and spirit of this invention.

I claim as my invention:

1. A lead wire terminal comprising a body member having a socket adjacent one end thereof, a pocket stamped up adjacent the socket end of the body member, band members stampedup in the said body member so that the bared end of a lead wire may be received between the said bands with its extremity lying in said pocket, an outturned partextending at an angle from the opposite end of the body member, and .a clamp at the extremity of the outturned part, the said clamp being adapted to engage the insulation at the end of a lead wire.

2. A lead wire terminal comprising a body member formed of an obverse and a reverse plate, bands stamped up in opposite directions from the said plates and adapted to receive the bared end of an insulated lead wire, and a clamp adapted to engage the insulation at the end of the wire.

3. A lead wire terminal comprising a body member having an obverse plate-and a reverse plate, a pocket formed in the reverse plate, a band member stamped up in the of the said plates, a pocket stamped up in V the reverse plate, band members stamped up in the obverse plate so that the bared end of the lead wire may be received be tween the said bands and pocket, an outturned part connected to the Opposite end of the reverse member, and a Li-shaped clamp at the extremity of the said outturned part, the said clamp being adapted to engage the insulation at the end of a lead wire.

5. A lead wire terminal comprising a body member having an obverse plate and a reverse plate, a socket formed in one end of the said plates, band members stamped up in the obverse plate in spaced positions, a pocket stamped up in the reverse plate, a band also stamped up in the reverse plate so that the bared end of a lead wire may be received and secured between the said bands and pocket, an outturned part at the other extremity of the reverse plate, and a U-shaped clamp connected to the outturned part adapted to engage the insulation at the end of a lead wire.

Signed by me this 5th day of July, 1917.
